Integrated resource plan

Puget Sound Energy (PSE) is developing an integrated resource plan (IRP) that identifies how we provide cost-effective electricity to reliably meet our customers’ needs for the future. The 2021 IRP will outline PSE’s plans to eliminate coal from its electric portfolio of resources and transition to carbon free generation by 2045.

The 2021 IRP will be completed by April 2021. The Draft 2021 IRP will be available in January 2021.

The last IRP was filed in 2017. The 2019 IRP process did not result in an IRP filing. The materials from the 2019 IRP process are available along with a Progress Report which was filed with the Washington Utilities and Transportation Commission (WUTC) in November 2019. 

2019 IRP meeting schedule and materials

Between May 2018 and September 2019, ten formal 2019 IRP public participation meetings have been held and the meeting record is provided below. In December 2019, a webinar was held concerning the details of the social cost of carbon methodology and related results for scenarios comparing the social cost of carbon adder to a tax.

On October 28, 2019, the Washington Utilities and Transportation Commission Staff filed a Petition for Exemption from WAC 480-100-238 pursuant to WAC 480-07-100 until December 31, 2020. On November 7, 2019 the WUTC held an Open Meeting concerning this matter and subsequently issued Order 2, exempting PSE (and other investor owned utilities in Washington) from WAC 480-100-238.

Pursuant to Order 2, PSE filed an IRP Progress Report on November 15, 2019.  On December 10, PSE filed a Revised Progress Report:

Documentation of the public participation process for the 2019 IRP is included below. The IRP Advisory Group (IRPAG) and the Technical Advisory Group (TAG) were teams of external stakeholders and regulators who met to provide input during the integrated resource planning process.

The 2021 IRP will be filed with the Washington Utilities and Transportation Commission on or before April 1, 2021. This website will be refreshed when the 2021 IRP public participation process commences.
